Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Mix all ingredients in a bowl at night.
Pour the mixture into baking pans and let it rise.
Bake in a 400°F (200°C) oven until golden brown.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs: Add structure and richness, helping the bread hold its shape as it bakes.
Flour: Forms the structure of the bread as its proteins set during baking.
Yeast: Produces gas that makes the mixture rise before baking.
Butter: Adds fat for a tender crumb and rich flavor.
Sweet milk: Adds moisture and softness to the dough.
White sugar: Feeds the yeast and adds sweetness and browning.
